Error in xamarin.kotlin.stdlib ($ReflectSdkVersion is defined multiple times) after migration from Xamarin.Forms

问题

以下是您的内容的翻译：

在过去的几天里，我一直在努力将我的应用从Xamarin.Forms迁移到MAUI。我已经解决了数十个错误，但这个错误让我无法理解。

错误：

MSBUILD：java.exe错误JAVA0000：.nuget\packages\xamarin.kotlin.stdlib.8.10\buildTransitive\net6.0-android31.0....\jar\org.jetbrains.kotlin.kotlin-stdlib-1.8.10.jar:kotlin/internal/jdk7/JDK7PlatformImplementations$ReflectSdkVersion.class中的错误：

2&gt;MSBUILD：java.exe错误JAVA0000：kotlin/internal/jdk7/JDK7PlatformImplementations$ReflectSdkVersion.class

随后是数百个警告，如下所示：

2&gt;JAVAC：警告：未知的枚举常量Scope.LIBRARY
